Reece Irving said that while it was exhausting it was achievable in those conditions.
"We were lucky that today's pool was 25 degrees, the reality is the ocean or lake you would be exhausted, freezing and wearing heavy clothes and it would be nearly impossible to get one of these on."
Another participant Adrian Heays said that while you can figure out how to put them on while in the boat, in the water they look completely different and it's hard to know where to start.
"It was a really valuable exercise, because you quickly learn how tough it is to put one of these on while in the water and adjust the straps. It goes back to the important message to get it on or it's no good," he said.
Tony Pearce said he couldn't believe that the inflatable lifejackets didn't float.
"Before we completed the exercise we threw a few inflatable lifejackets, that hadn't had their cord pulled, into the water and found that within 10 seconds they had sunk. While you would normally be wearing one of these it was really interesting."
